等张运动与等长运动对高血压患者血脂及内皮素的影响

Responses of Blood Lipid and Plasma Endothelin to Isotonic Exercise and Isometric Exercise in Hypertension

目的:比较等张运动与等长运动对高血压患者的血脂及内皮素的影响,为高血压病运动处方的制定提供理论依据。方法:将45例老年高血压患者随机分成主要基线资料具有可比性的三组,A组采用等张练习,B组采用等长练习,C组采用等长练习+等张练习。观察运动训练16周后血脂及内皮素的变化。结果:A、B组对高血压患者的血脂有一定的改善作用,血浆内皮素降低(P<0.05);C组训练前后相比较,TC、LDL降低(P<0.05),TG显著降低(P<0.01),HDL则明显升高P<0.05),血浆内皮素显著下降(P<0.01)。结论:等张运动与等长运动相结合的全面康复训练方案可以有效改善高血压患者血脂及内皮素水平,有利于高血压病的康复,是高血压病运动处方的首选。

The paper is to compare the difference of the response of blood lipid and plasma endothelin to isotonic exercise and isometric exercises, and give the theory foundation for making exercise prescription for hypertension. Forty-five old age hypertension sufferers were randomized into group A, group B and group C, with heart rates as target and equal exercise times different exercise projects carried out, and isotonic exercise for group A, isometric exercise for group B, isotonic exercise and isometric exercise together for group C. Patients in the three groups were well-matched in terms of basic data. Both sixteen weeks exercise-included changes in blood lipid and endothelin-1 were observed. The result showed that blood lipid of all objects becomes appreciably reduced, , and the level of plasma endothelin becomes lower, but it is more remarkable in group C(P<0.01). It's concluded that the all rounded training including isotonic exercise and isometric exercise can improve the function of vascular endothelial to a certain extent, can reduce the blood lipid evidently, and it is the first select for exercise prescription of hypertension.
